Influence of HDI as a cathode film-forming additive on the performance of LiFe_0.2Mn_0.8PO₄/C cathode

摘要

Herein, we construct a polymer protective layer on LiFe_0.2Mn_0.8PO₄/C particles with hexamethylene diisocyanate via the onium ionization–polymerization reaction. This membrane obviously improves LiFe_0.2Mn_0.8PO₄/C's rate capability and cyclic stability. It exerts a more significant effect on samples with less carbon, demonstrating its function to ameliorate the conductive network.
